MAGAZINE ADJUSTING DEVICE FOR TYPOGRAPHICAL COMPQSING MACHINES Filed May 25, 1932 Patented Jan. 2 1934 MAGAZINE ADJUSTING DEVICE FOR TYPO- GRAPHICAL COMPOSING MACHINES Christian Augustus Albrecht, Berlin, Germany, assignor to Mergenthaler Linotype Company, Brooklyn, N. Y., a company of New York Application May 25, 1932, Serial No. 613,401, and

in Germany 9 Claims.

' In typographical composing machines, having a plurality of magazines it has already been proposed to raise and lower the magazines to adjust them to their respective operative positions, by means of cams which are actuated by a crank handle or lever located in proximity to the keyboard. In cases involving a considerable range of adjustment and consequently a considerable throw of the cams transmitting gear has been employed, preferably a bevel gear, and the shaft of the cam disc extending in the longitudinal direction of the machine has been rotated by a crank handle, actuated in a plane parallel with the front of the machine both for efiecting achange of magazines in the operative position, and for elevating the magazines beyond the operative position for the purpose of removing them from the machine.

According to the invention, two independently operated mechanisms are provided for controlling the cam shaft, to be employed respectively for shifting the magazines in the operative position and for elevating the magazines beyond the operative position, at least one of these mechanisms being actuated by a simple fore-and-aft movement of a lever located in the vicinity of the keyboard of the machine whereby the operation is simplified without providing, as has heretofore been proposed, separate devices for engagement withthe machine frame for effecting the raising of the magazines beyond their operative position.

i In the accompanying drawing, two constructlonal forms of the invention have been illustrated. In the said drawing:- 7

Figure 1 is a side elevation of suflicient of a composing machine to illustrate the application thereto of one constructional form of the invention;

Figure 2 is an elevation, partly in section, as viewed from the right-hand side of Figure 1;

Figure 3 is an elevation, partly in section, corresponding to the left-hand portion of Figure 2, showing a modified constructional form, and

Figure 4 is an elevation of the lever mechanism as viewed from the right-hand side of Figure 3.

r In the constructional form of machine 'illustrated by way of example, there are provided two magazines (2, a which are supported on a frame 17, which is adapted to rock about a pivot (not shown) located at its upper end for effecting the adjustment of the lower ends of the magazines,

relatively to the assembler entrance n. The frame I) is provided at its lower extremity with a May 27, 1931 lug or projection c, which carries a roller adapted town in the groove of a cam disc d.

The cam disc d, is mounted upon a shaft e, supported in the machine frame ,1. One end of the shaft e, extends beyond the adjacent part of the machine frame, and is supported loosely in a bush or sleeve g, which is located between the shaft and its bearing. This sleeve 9, on its outer end, is provided with a clutch member adapted to be engagedwith a co-operating clutch inemberon the adjacent hub of a hand wheel h feathered on the outer end of the shaft e. The hand wheel h is thus not rotatable independently of the shaft e; but is axially movable thereon for the purpose of being coupled with and uncoupled from the sleeve 9. To the sleeve 9 is rigidly secured a boss 70, provided with two arms 2, i The arms i are connected with the escapement rods-by means, not shown in the drawing, which effect the disengagement of said rods from the escapement mechanisms during the movementof the magazines, whilst the arm 11 is connected to a lever n by means of a link m, the said lever being adapted to rock about a stationary axis 0 on the machine frame, and being also provided with a handle p. Pivotally connected to the magazine frame I), are two bars q, q each provided with an adjustable collar 7", r two counterbalance springs t, t are each adapted to bear at one end against the respective collar and at the other end against a lug or boss 8, or .9 which latter are provided with openings for guiding the bars q, q I

The bush 9 is normally coupled with the shaft e through the clutch connection with the hand Wheel h as shown in Figure 2. Hence, when the lever 1t is swung from one to another of the two positions shown respectively in full and dotted lines in Figure 1, the shaft e will be rocked and the cam disc d, mounted thereon will raise or lower the magazine column, in order to bring one of the magazines a, a into the correct operative position relatively to the assembler entrance u. During this movement, and in the customary manner, the escapement rods will simultaneously be brought out of engagement with the escapement mechanisms of the magazines by the arm 1'.

' In order to maintain the device in its two terminal positions any preferred stops, detents or the like, not represented in the drawing can be used.

In order to raise the magazine column beyond its'operative position, so that the lower magazine, for example, can be removed from the machine, the hand wheel h is drawn outwardly along the shaft e in order to uncouple it from the bush g, and then turned so as to also turn the shaft e and the cam d without affecting the hand lever 10 and associated mechanism.

When the portion of the cam indicated by the dotted circle 12 in Figure 1 comes into engagement with the roller 0 the magazine column occupies its highest position, and the magazine can be removed. The dotted circle 0 indicates the portion of the cam d which engages the roller 0 when the upper magazine is adjusted to operative relationship with the assembler entrance u.

The alternative constructional form of the invention illustrated in Figures 3 and 4 may be conveniently employed to obviate the necessity of the operator leaving his seat at the front of the machine when effecting the elevation of the magazines beyond their operative position, and also in cases where the machine is provided with auxiliary magazines occupying the space which otherwise would be available at the side of the main magazines for access to the hand wheel h.

In the said constructional form, a hand lever at extending into close proximity with the keyboard, is substituted for the hand wheel h, and the connections next to be described are provided for enabling the said hand lever to be operated independently of the hand lever p which latter is employed, as in the before described construction, for effecting the adjustment of the magazines in their operative positions.

The hand lever a: is pivoted upon the shaft e, and in order to prevent displacement of the lever axially of the shaft, a pin in the hub of the lever engages an annular groove e in the shaft. Between the hub of the lever a: and the adjacent face of the bush 9, the shaft :2 carries a grooved collar to which is feathered to the shaft and is provided with a pin 10 one end of which is adapted to engage a recess in the face of the bush 9, and the other end of which is adapted to engage with a recess 0: on the inner face of the hub of the lever x. The annular groove of the collar w is engaged by a fork y pivotally mounted at g on the hand lever :13.

The fork y constitutes one arm of a lever whose other arm y is pivotally connected to a rod 2 slidably mounted in a longitudinal recess in the hand lever 00. The rod 2 is encircled by a spring 2 which acts between a shoulder a on the rod and a web 2 in the hand lever :6, through which web the rod 2 passes. The lower end of the rod 2 is fitted with a finger grip 2 which extends through an aperture in the lever :c in close proximity to the handle :c of the said lever. The spring 2 constantly tends to hold the collar to in the position shown in Figure 3, with the pin w in engagement with the recess in the bush g. As the bush g is thus normally coupled with the shaft 6 the shifting of the magazines into their respective operative positions may be effected by the manipulation of the handle p as in the construction illustrated in Figures 1 and 2.

7 When it is desired to elevate the magazines beyond their uppermost operative position, the handle m is grasped and with one finger the grip 2 is brought down against it. Consequently, the ring 10 will be moved towards the left, as viewed in Figure 3, against the action of the spring 2 so that the bush 9 will be uncoupled from the shaft e; on the other hand, the pin to will be engaged with the recess .10 of the lever at, so as to couple that lever with the shaft e. When the lever so is then swung, the magazines will be elevated beyond their uppermost operative positions.

It is to be understood that the constructional forms of the invention hereinbefore described and illustrated in the accompanying drawing are taken as convenient examples, and that various modifications may be made without departing from the scope of the invention. For instance, if it is desired to apply the invention to a machine in which the magazines are raised and lowered in a direction perpendicular to their plane of inclination, one or more additional rollers 0 may be provided on the magazine supporting frame I) to engage with a corresponding plurality of simultaneously actuated cams d. Further, the lever n for effecting the adjustment of the magazines in their operative position, may be replaced by a reotilinearly movable member having appropriate connections with the shaft 6, and any suitable coupling devices may be employed for the connection and disconnectionof the bush g and the hand wheel h or lever ac. The invention is therefore not limited to any specific form or embodiment except in so far as such limitations are specified in the claims.
